Energy Profiling Home Appliances

Plogg Provides High Resolution Analysis of Energy Consumption for Consumer Appliance Manufacturers

GRIMSBY, England, March 21, 2011 - The Plogg from Energy Optimizers Limited (EOL) is used to evaluate the
energy performance and profile of electrical appliances based upon actual
consumer behaviour.

The plogg is a combined smart meter plug and data logger. It can be
attached to any electrical appliance or device that uses a standard mains
socket in Schuko, UK, French or USA formats. The Plogg is able to measure the
electrical energy consumption of connected devices and appliances at high
levels of resolution, up to 1 minute as standard and at higher levels of up
to 2 seconds in customised versions.

The benefit for appliance manufacturers is the capability to use the
Plogg in field trials unobtrusively in order to observe consumers' behaviour
and actual patterns of use during each duty cycle and at time of use, whether
daily or weekly. This valuable data assists the manufacturer in identifying
the commonly used operating programs and to optimise the energy efficiency of
the appliance based upon actual behaviour patterns rather than simulated
laboratory tests.

Data logging on the Plogg can be set to either Event dependence or Time
dependence. In the former case the logs are captured only at predefined set
points, when the appliance is switched on or off and when the power (Watts)
exceeds certain limits, imitating the various cycles used in the appliance.
Alternatively, the Plogg can be set to monitor the appliance based on time
dependency only to capture detailed data about the performance of the
appliance. The logs are stored on the Plogg until downloaded to a PC locally
or remotely via the internet.

"The ploggs provide the level of detail that is needed to understand the
behavioural use of connected appliances," said Ollie Smith, Director,
Telegesis UK Limited, "Furthermore, the resulting data can be acquired easily
through the embedded wireless ZigBee communications."
